Question about Toshiba Satelite 2405-S201 Notebook

1 Answer

Memory system appears to have to have a memory limit of 512mb. Can this be corrected. I tried all types of memory configs,but message comes up saying please install 512mb or less. this seems absurd in a p4 1.6ghz. The message comes up during post from within the notebooks firmware. any help would be appreciated. Thanks Frank Velez Frankvelez1@hotmail.com

IBM T23 wont turn on after adding new RAM


Hi - according to memory suppliers your T23 has the following memory capacity / requirements:

  • IBM ThinkPad T23 maximum RAM capacity: 1GB
  • Your IBM has Two (2) memory slots or sockets
  • Module upgrade PIN count is: 144-PIN
  • The memory speed is: SDRAM 133MHz, PC133
  • The laptop DIMM type for the ThinkPad T23 is: SODIMM, SO-DIMM, Small Outline DIMM
  • Non ECC

If you are meeting these requirements, you may have a defective module.

Also, according to Lenovo's page on the machine:

Memory
The system has 128MB or 256MB of memory standard and can be configured for up to 1GB of addressable memory. Memory options up to 512MB SDRAM SO DIMMs each can be added in the two available slots for memory expansion. The standard 128MB of memory is expandable up to 640MB and the 256MB of memory is expandable up to 768 MB of addressable memory with 64, 128, 256, or 512MB SO DIMMs without removing the 128MB SO DIMM that is standard in one of the internal slots for memory. For customers that need the maximum 1GB to which memory can be expanded, it is necessary to replace the 128MB or 256MB card with a 512MB card plus add another 512MB card in the extra slot. Only 133MHz DIMM memory can be used in this system. The use of 100MHz DIMM memory is not supported in the T23 systems.

This means yo can trouble shoot the 512MB modules individually by installing one of the original 128MB modules and one of the new 512MB modules (for a total system memory of 640MB). If it does not boot, try again with the other 512MB module. This will help you identify a defective module that may be preventing the machine from booting.

I hope this helps & good luck!

Adding computer memory


The only thing you could do is put in a 256MB module in the slot that you have access to. Only one socket is user upgradable. The second socket is only upgradable by a Dell service center. They would have to install a second 256 module to get you to the 512MB max.

I HAVE (4) 1501 ALL ARE DOWN, 1- SAYS CAN NOT FINE OPERATING SYSTEMS, 1- SAYS DISCARD ALL MEMORY


For the one where the operating system is down, start it up @Dell logo press Ctrl and F11 and try factory restore, this may cure it....if not you will need to get hold of a disk etc
for the one that says discard all memory, (I advise anti static wrist bands be worn when handling any components, turn off and remove battery) first i would check the correct memory is in it, you may need to research though i think 512MB-533MHz DDR2-533 PC2-4200, 200p SODIMM, 1.8v (is the correct one) If theres more than one stick try them one at a time make sure they are seated correctly and free from dust or visable damage try return the bios (usually entered by f1 del etc instructions on screen at boot) to default settings save and try If all fails then the memory could be dead
hope this helps a little

I have a Toshiba Satellite 1905-S301 that has 512mb of DDR memory currently. I have a stick of 128 that I was going to throw in there to boost performance but when I opened the compartment the there was...


There are 2 types of memory, one for laptops and one for pc.

Your additional stick seems to be for pc from what your saying.

Additional thoughts:
I'm sure you can buy sticks for laptops at walmart or whereever you bought ur laptop. Just make sure it is the same speed type. Example: yours is 512mb ddr PC 5200, you will need to find PC5200, the 512mb and up you shouldnt have to worry about. So do your research before you upgrade or you will burn your laptop.

Wont recognize new memory?


First try to reseat the memory, if it is still showing the same amount, then you may have a bad stick of memory, remove both and insert 1 stick into Dimm 1 slot and see if it still registers 894, then put the other in the same slot and see what it registers. Then try in the Dimm2 slot and see if you get a different reading Depending on the manufacturer, it may only show that amount since Windows shows memory different that the memory manufacturer.

Hope this helps.

I have a Satellite 2405-S221 and I was wondering if the max memory i can install is 512K, is there a way to update the bios, or ANYTHING to increase that amount to at least 1 gig??


Toshiba Satellite 2405-S221 Laptop takes the PC2100 DDR SDRAM SODIMMs Memory Type, and comes installed with 256 MB (removable) of Memory. You can upgrade your Toshiba Satellite 2405-S221 Laptop to up to a maximum of 512 MB Memory, the system has 2 sockets to install Memory, already with 256 MB (removable) standard Memory installed.

In short.... yeah, 512k is the max.

Doesn't appear to a bios limitation. It is a hardware issue that is limiting the amount.

Error message after installing memory ram upgrade.....


The memory appears to be the right kind.

Try installing just one 1GB module, and run the diagnostics (press F12 at boot time and select diagnostics).

Good luck!

Memory upgrade


We have the memory you need. Memory-Up is committed to provide the best memory and excellent services for all of our customers. We know that sometimes it is a bit confusing to buy the correct type, speed, and capacity of memory for your system. Therefore we hope that these tips below would help you for buying the new memory.
Memory Upgrade Tips

What is Compatibility and Memory Density Issue?

Memory module can be composed using different type of memory chips and therefore created different type of density for the module. For instance, a 512MB PC2700 DDR SODIMM memory can be composed using eight 32x16(High Density 512Mb technology) memory chips or sixteen 32x8(Low Density 256Mb technology) memory chips. As the laptops are equipped with different memory chipsets, some older laptop (chipset) would have compatibility issue working with the modules that is built with the newer 512Mb technology. Using the Not-Compatible memory will result the laptop to either not boot or only recognizing half of the memory modules. Thus that is not the correct memory for your system. Our Memory Finder and Memory Scanner will help to eliminate those problems and find the correct memory for you. We guaranteed the memory to work or your money back. 

How much memory do I need?

Here are some general descriptions for different type of users and the amount of memory they would need for their systems.

Normal User: The system is mainly used for checking e-mails, processing word/excel file, and web surfing. Suggestion: 512MB to 1GB of system memory. 

Power User: The system is mainly used for playing computer games, editing photos/videos, running database queries, or multi-tasking environment. (Surfing web/Processing Word/Excel File/Listening to Music). Suggestion: 1GB to 2GB of system memory.

Super User: The system is mainly used for running large number of database queries, professional editing of photos/videos, heavy multi-tasking environment. Usually a server or a workstation would be considered as Super User due to the multiple accesses from users. Suggestion: 2GB and above of system memory.

How much memory and memory slot do I have with my system? 

You can download our Memory-Scanner to find out the the amount of memory that you have and the memory slots that are available for upgrade. 

How many memory module should I buy?

It is recommended to purchase one module with bigger capacity than two modules with smaller capacity. For instance, if you can buy either one 1GB memory module or two 512MB memory modules for your system, it is recommended to get one 1GB and leave the other memory slot empty for future upgrade if necessary. 

Note: For systems that supports dual channel memory mode, although memory modules need to be installed in pairs to enable Dual Channel Memory Mode, we still recommended users to purchase one bigger module than two smaller modules since Dual Channel Memory Mode has only a minimal improvement in the actual system performance.

What if I want to mix different memory together?

Different sizes/speeds of memory can be used together as long as their specification are qualified by the systems. For instance, a laptop can use one 256MB and one 1GB of memory for the total of 1.25GB system memory. Mixing two different speeds of memory modules would result the system to run at the speed of the slower memory between the two modules. We recommend users to use our Memory Finder or Memory Scanner to find the correct memory for your system.

Toshiba satellite a100,wa-1 memory upgrade


Hi,

Take out all the memory cards and wipe the gold part of the memory modules.

Then insert the two 512 modules & check the memory.

If it shows the correct readings, then the two modules are detected.

Then insert the 1 gb & other one 512 module.

If it shows the correct readings, then the two modules are detected.

Then use the other one gb with the same 512 & check if it shows the correct readings.

Then the two 2 gb modules are fine.

Now insert the two 1 gb modules & check now.

There are ECC type & non-ECC type memory modules are available, chck which one your computer supports & which type you have.

If it shows the correct readings, then the two modules are detected and fine.

Then you can also swap the slot and check if any memory module is not detectd correctly.

Some have four slots & i dont know how many slots your laptop have.

Good Luck.

Live, Love, Laugh.

According to this link, the memory of Compaq Evo N610c can be upgradable to 1024 mb.

http://h18000.www1.hp.com/products/quickspecs/11382_div/11382_div.HTML

Memory Upgrade for Compaq Evo N610C, the Compaq Evo N610C takes the PC2100 DDR SDRAM SODIMMs Memory Type, and comes installed with of Memory. You can upgrade your Compaq Evo N610C to up to a maximum of 1.0 GB Memory, the system has 2 sockets to install Memory, already with standard Memory installed. For best system performance use the maximum amount of allowed Memory per slot for your system. (Souce: http://www.memorystock.com/memory/CompaqEvoN610C.html)

So you have to install 512mb memory module on each slot to make up 1024mb of memory.

Did you install 512mb memory module on each slot or did you just install 1GB memory module in one slot?

Try to go back to 256mb RAM and see if you will have the same blue screen error. If you did not receive any blue screen, try to add memory into it or just insert 512mb first and then oserve again if you will have the blue screen error.

You may also want to go to these links for other suggestions.
